CHAPTER 4
CALIBRATION AND ADJUSTMENT
The PTB210 series barometers can be fine adjusted and calibrated
against pressure standards that have high accuracy and stability as
well as known traceability to international standards. By comparing
the output to a reference, the user can define the corrections required
for readjustment.
NOTE Calibration is considered not to involve any adjustments.
It is advisable to write down the previous corrections so that they will
not be lost by mistake.
The corrections are given by using the Wizard software; available for
download at
http://www.vaisala.com/PTB210Wizard/ . Finally, the
barometer is calibrated to verify its real accuracy.
Wizard Software
